REXROTH VT-VSPA1-1-F10 Proportional Valve Amplifier – VT-VSPA1 Series
Imagine a high-speed injection molding line mid-cycle, or a steel mill’s rolling press holding critical tonnage — and the proportional valve loses its command signal. Without a precision amplifier card like the VT-VSPA1-1-F10, the valve defaults to an undefined state: pressure spikes, actuators drift, and the entire process halts. Unplanned downtime in heavy industry doesn’t just cost minutes — it costs thousands per hour. The REXROTH VT-VSPA1-1-F10 is the electronic intelligence that stands between controlled motion and catastrophic process failure.
The VT-VSPA1-1-F10 is a single-axis proportional valve amplifier card from Bosch Rexroth’s VT-VSPA1 series — a benchmark product line in industrial electrohydraulic control. Designed to drive proportional directional control valves and pressure/flow valves, this amplifier card delivers stable, repeatable analog command processing with integrated enable logic and ramp function generation. It occupies a trusted position in global hydraulic automation, deployed across press machinery, die casting, marine systems, and process industry installations worldwide.

Key Features & Benefits
- Precision Analog Command Processing: Accepts ±10 V differential command signals with high linearity, ensuring accurate valve positioning across the full stroke range.
- Integrated Ramp Generator: Independent ramp-up and ramp-down adjustment prevents hydraulic shock and pressure surges during valve transitions — critical for protecting actuators and piping.
- Digital Enable Logic: Clean enable/disable switching eliminates valve hunting at startup and shutdown, improving system safety and repeatability.
- Compact Euro Card Format: Designed for standard rack-mount enclosures, simplifying integration into existing Rexroth VT-series control cabinets without additional hardware.
- Robust Industrial Design: Built to Rexroth’s industrial-grade standards for continuous-duty operation in demanding factory environments.
- Direct Solenoid Drive: Current-regulated output compensates for solenoid coil resistance variation due to temperature, maintaining consistent valve response.
Industry & Equipment Applications
- Plastics & Rubber: Injection molding machines, blow molding, extrusion lines — precise pressure and flow control during mold filling and holding phases.
- Metal Processing: Hydraulic presses, forging presses, rolling mills — force and position control under high-load conditions.
- Die Casting: Shot control and intensification phase management in aluminum and zinc die casting cells.
- Marine & Offshore: Steering gear, stabilizer fin control, hatch actuator systems requiring reliable proportional valve drive.
- Mobile Hydraulics: Industrial vehicles and cranes where smooth, proportional motion control is essential for operator safety.
- Process Industry: Chemical and petrochemical flow control loops integrating electrohydraulic actuation.

Frequently Asked Questions
Q: What is the difference between VT-VSPA1-1-F10 and VT-VSPA1-2-F10?
A: The suffix “1” and “2” typically denote single-axis and dual-axis configurations respectively within the VT-VSPA1 series. The VT-VSPA1-1-F10 is a single-axis card. Please confirm your valve circuit requirements before ordering.
Q: Can the VT-VSPA1-1-F10 be used with non-Rexroth proportional valves?
A: In principle, the card outputs a current-regulated signal compatible with many proportional solenoids. However, Rexroth designs and validates this card for use with their own valve range. Compatibility with third-party valves must be verified against solenoid coil specifications.
Q: Do you supply the matching rack enclosure and power supply?
A: Yes. We can source compatible VT-VSPA1 series rack hardware. Please include your full system requirements in your inquiry.
Q: What is the typical lead time for this part?
A: Lead time depends on current stock levels. In-stock units ship within 3–5 business days internationally. For out-of-stock items, lead time is typically 2–4 weeks. Contact us for real-time availability.
Q: Can you provide a datasheet or wiring diagram?
A: Yes. Official Rexroth documentation references are available upon request. Contact [email protected].
